Abernethy Road is a 14.7-kilometre (9.1 mi)[clarification needed] long minor arterial road linking Belmont with the Great Eastern Highway Bypass in Hazelmere, a suburb of Perth, Western Australia.

In 2014, an on-ramp joining with Tonkin Highway where Abernethy Road passes underneath was constructed, as part of Gateway WA.

The road ends at the Great Eastern Highway Bypass, which provides alternative access to South Guildford (to the west) or to Bellevue and Midland.

[6] A new ramp from Abernethy Road to Tonkin Highway southbound was constructed as part of the $1 billion Gateway WA project.

[7][8] Construction of the ramp, and the Gateway WA project, officially began on 1 February 2013 with a groundbreaking ceremony attended by the state and federal transport ministers, Troy Buswell and Anthony Albanese, and was opened to the public in early 2014.
